Receive Coil for Low-field NMR Scanner Optimized Using Inductive Coupling
نویسندگان
چکیده
The paper describes a receive coil system for low-field NMR scanner intended for cardio measurements. The coil system is based on good qualities of surface coils accommodating them to volume measurements. The active volume of the coil is widened using two inductively coupled resonators. Signal from the coil system is amplified using a highimpedance preamplifier thus no special matching is necessary. The coil can be utilized for larger samples measurements. Thanks to inductive coupling the coil system need not be retuned before every new measurement. Performed experiments confirmed good agreement between the theory and the practice but should be verified by more experiments.

Transmit Coil Decoupling of 8-Channel Coil Arrays with Ultra-Low Output Impedance RF Power Amplifiers
Introduction: In previous work, an ultra-low output impedance RF power amplifier (RFPA) was introduced to reduce the effects of inter-element inductive coupling in parallel transmit arrays [1]. It uses an output-matching network to transform the MOSFET drain-source impedance into a very low value to suppress inter-element coupling effects while matching the coil input impedance to the optimum l...
متن کاملDesign Optimisation of an Field Free Point Magnetic Particle Imaging Scanner
Introduction Magnetic Particle Imaging (MPI) is a new imaging technology aimed at the imaging of a tracer in the human body. First published in 2005 [1], the number of scanner prototypes is growing and there is always more room for optimisation in each new scanner design. The imaging principle is based on the non-linear magnetisation of magnetic nanoparticles. Placed in a magnetic field they ca...
متن کاملOptimization of a high sensitivity MRI receive coil for parallel human brain imaging
Two eight-channel MRI receive-only coils were developed to provide whole-brain coverage at 1.5 T and 3.0 T field strength, respectively. Objectives were an image signal-to-noise ratio superior to standard designs throughout the human brain, as well as high parallel imaging performance. Electro-magnetic field simulations were used to determine array diameter and inter-element coil gap. Low mutua...

متن کاملAssessment of the Characteristics of MRI Coils in Terms of RF Non-Homogeneity Using Routine Spin Echo Sequences
Introduction: One of the major causes of image non-uniformity in MRI is due to the existence of non-homogeneity in RF receive and transmit. This can be the most effective source of error in quantitative studies in MRI imaging. Part of this non-homogeneity demonstrates the characteristics of RF coil and part of it is due to the interaction of RF field with the material being imaged...
